JOHN LEWIS STEIIZ, OF CHICAGO, ILLINOIS.

COOLER FOR LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 749,238, dated January12, 1904. Application led November 14, 1902. Serial No. 131,306l (Nomodel.)

To a/ZZ whom, t may concern:

Be it known that I, JOHN LEWIS STEITZ, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented new and useful Improvements in Coolers for Liquids, ofwhich the following is a full, clear, and exact description.

This invention relates to improvements in cooling devices for liquidsunder pressuresuch, for instance, as beer-the object being to provide asimple andinexpensive device for this purpose designed tobe placed in abox of cracked ice and not liable to be broken or injured by the ice, asoften happens to the usual coiled pipes.

Other objects of the invention will appear in the general description.

I will describe acooler for liquids embodying my invention and thenpoint out the novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a perspective view showing a cooler embodying' my inventionas arranged in place. Fig. 2 is a side elevation of a member of thecooler. Fig. 3 is an elevation, partly in section, on the line m Of Fig.2. Fig. 4 is an elevation of a member of the cooler, showing the sideopposite that shown in Fig. 2; and Fig. 5 is a section on the line y yof Fig. 4.

The cooler comprises a series of metal boxes or casings. I have hereshown four of these casings 1v 2 3 4 as connected together; but it is tobe understood that a greater or less number may be employed,dependingupon the conditions or requirements. Each casing has its side wallscorrugated or fluted, so as to provide a greater area for contact withthe ice. The liquid to be cooled is designed to pass through the severalboxes or casings. The liquid passes into the first casing l through apipe 5,` which communicates with the upper end of said first casing.From this casing l the liquid passes through a tube 6., connecting thelower portion of the casing l to the casing 2, and the upper portion ofthe casing 2 is connected to the upper portion of the casing 3 by a tube7, while the lower portions of the casings 3 4 communicate through atube 8, and from the upper portion of the last casthe upper portions ofthe casings 3 4 are connected by a coupling l2. These couplings are eachprovided with a small bore, which will permit the passage of air, butwill not permit the passage of liquid to any considerable extent. Theair passing through the couplings 1l l2 and also through the tube 7 willpass out through the faucet l0 when opened.

In using the device a series of the coolers is to be placed inconnection with the pipe leading from ,each keg to a faucet, and thesedevices will of course be arranged in an icebox 13, arranged underneaththe bar and in which cracked ice is designed to be placed. Whenan oddnumber of boxes or casings are employed, a feed-pipe leading from thekeg will pass into the lower portion of the first section, as indicatedby dotted lines in Fig. 2. Each casing at its lower end at one side isprovided with a perforated lug 14, by means of which the lower portionsof adjacent casings may be secured together by bolts passed through theperforations.

Having thus described my invention, I claim as new and desire to secureby Letters Fatent- The combination with an ice-box, a pipe leading froma source vof liquid-supply and a valved outlet-pipe, of a coolerarranged in the ice-box and comprising a series of casings communicatingalternately at the top and bottoni, air-tubes connecting adjacentcasings at the top, connections between the inlet-pipe and the firstcasing of the series, a connection between the outlet-pipe and the lastrcasing of the series and a perforated lug at the lower end, at one sideof each casing whereby adjacent casings may be secured together.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN LEWIS STEITZ.
